Activity 01
Clean Water, Dirty Water Jar
Prepare two large, clear jars of water. In one, add soil, small bits of paper, and a drop of oil to make it 'dirty'. Leave the other one clean. Ask students to describe and compare the two jars, discussing which one they would drink from and why.
Identify something that makes water dirty.
Facilitation TipUse a magnifying glass to let students look closely at the particles in the dirty water to make the experience more engaging.
What to look forShow students two pictures: one of a clean pond with fish and birds, and one of a dirty pond with rubbish. Ask them to point to the healthy pond and give one reason for their choice.

Activity 02
Water Hero Sorting Game
Create picture cards of things that make water dirty (e.g., plastic bag, factory pipe, leftover food) and things that help keep it clean (e.g., dustbin, water filter, person planting a tree near a river). Students sort the cards into two piles: 'Makes Water Sad' and 'Makes Water Happy'.
Explain why we should not throw rubbish into a river.
Facilitation TipAfter sorting, have each group explain their choice for one 'sad' card and one 'happy' card to reinforce the concepts.
What to look forDuring a class discussion, ask students to do a 'thumbs-up' if an action helps keep water clean (e.g., using a dustbin) and 'thumbs-down' if it makes water dirty (e.g., throwing a bottle in a lake).

Activity 03
Story of a River
Tell a simple story about a happy, clean river that becomes sad and sick because people throw rubbish into it. Use puppets or drawings to represent the river and the animals that live in it. Conclude the story by asking students how they can help the river become happy again.
Compare a clean pond with a dirty pond.
Facilitation TipEncourage students to make sounds for the happy river (splashing) and the sad river (slow, gurgling noises) to enhance participation.
What to look forAsk students to draw a picture of a river. On one side, they should draw things that make the river dirty, and on the other side, draw things that help keep it clean.

Start with visuals like pictures or short videos of clean and polluted rivers in India to create a strong impact. Use simple, relatable language, comparing a sick river to a person feeling unwell. Encourage storytelling and role-playing to help students empathise with the environment and understand the consequences of pollution.
By the end of this topic, your students will be able to identify things that pollute water and explain why it is very important for us and for animals to have clean water.
Watch Out for These Misconceptions
If water looks clear, it must be clean and safe to drink.
Water can look clear but still have tiny, invisible germs that can make us sick. That's why we should always boil water or use a filter before drinking it.
Throwing one small sweet wrapper in the river doesn't matter.
If everyone thinks their one small piece of rubbish doesn't matter, soon the river will be full of thousands of wrappers. Every little bit of rubbish adds up and harms the water and the fish living in it.
The rain will wash away all the dirt and make the river clean again.
While rain is fresh water, when it flows on the ground, it can pick up rubbish, chemicals, and dirt and carry it all into the river, making the river even dirtier.
